Refracting telescope - Wikipedia
A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses .

The Beginner's Guide to Refractor Telescopes - High Point Scientific
Simply put, a refractor is a type of telescope that uses a lens to bend (or refract) light to a point. The point where the light path intersects is called the “focal point”, and is where your eyepiece, camera, or diagonal would go. The length from the lens to the focal point is known as the “focal length” of the telescope.

Refractor Definition & Meaning - Merriam-Webster
The meaning of REFRACTOR is a telescope whose principal focusing element is a lens.

What Is a Refractor Telescope? An In-depth Explanation
A refractor (also known as a refracting telescope) is a type of optical telescope that uses a collection of lenses to form an image, using light.

What Is A Refractor Telescope? – Telescope School
A refractor telescope is composed of two lenses; an objective lens and an eyepiece. Light travels through the objective lens and is slightly bent (refracted) to create a focal point for the eyepiece to receive.

Refracting Telescope: Definition, Ray Diagram, and Examples - Science Facts
A refracting telescope, or a refractor, uses a combination of lenses to produce images of distant objects, e.g., stars and planets that would otherwise not be visible with the human eye. A simple refracting telescope is made up of two lenses, which are called the objective and the eyepiece.

Reflector vs Refractor Telescope: 7 Differences that Matter - The Optics
Putting it simply, reflector telescope, uses mirrors, while refractor telescope uses lenses. Both, however, have the same purpose, which is to explore the skies above us. There are lots of details, both minor and complex, to consider when choosing between the two.

Yerkes Observatory - Wikipedia
Refractor (Lens) A major contemporary for the Yerkes was the well-regarded 36-inch Lick refractor near San Jose, California. [64] The Yerkes, although just 4 inches in aperture larger, meant an increase of 23% in light-gathering ability. [64] Both telescopes had achromatic doublets by Alvan Clark.

Refractor vs Reflector Telescope: What is the Difference?
What is a Refracting Telescope? A refracting telescope uses a curved, convex objective lens at the front to focus light by bending light rays to a single focal plane. Usually, refractors use a lens made of multiple elements or pieces of glass, usually slightly different kinds of glass.

Refractor Telescopes - Astro_Observer
Refractor telescopes, also known simply as refractors, are among the most iconic and historically significant instruments in astronomy. Their elegant design and ease of use have made them a favorite for both amateur and professional astronomers.
